I have used Echinacea in the pill form in the past.
But after trying this product I will never go back. Nature's Answer is the most effective Echinacea I have ever used. If I know I may be exposed to people with colds or flu such as Christmas shoppers or at holiday festivities, I take Echinacea 2 days before, during, and 2 days after the potential exposure. Or if I feel a cold or illness creeping up on me, I begin taking Echinacea and continue it for 3-5 days. Keeps me well and at 70 years of age that's my goal.
